OIL BURNER.

Application filed May 27,

This invention appertains generally to new and useful improvements inburners and has more specific reference to a novel and simplified oilburner.

The primary object of the present invention is to provide such a burnerof the nature stated including an inverted burner nozzle and asuper-heater or generator whereby to insure a steadier and stronger flowof gas from the burner nozzle7 thereby eliminating the danger of blowbacks.

A further object of thepresent invention is the provision of a new andnovel type of burner nozzle.

Another object of the present invention is to provide such an improvedburner of the nature stated having associated therewith safety means forautomatically cutting off the supply of oil should the burner becomeflooded due to the going out of the burner4 nozzle.

A still further object of the present invention is to provide such aburner ofthe nature stated which while simple in construction, isnevertheless strong, sturdy and durable, one which is effective andefiicient in its operation7 one which can be manufactured and placed onthe market at a reasonable figure and one which is well designed for thepurposes for which it is intended.

lVith these and numerous other objects in view, the invention resides inthe novel construction, combination and arrangement of parts to be morefully hereinafter' described, illustrated in the accompanying drawingsand particularly pointed out in the appended claims.

In the drawings forming a part of this application and wherein likecharacters of reference denote corresponding parts throughout theseveral views:

Figure 1 is a side view, partially in section, 'f an oil burnerconstructed in accordance with the present invention.

Figure 2 is a top plan view thereof.

Reference now being had more particu-- 1 larly 'the accompanyingdrawings wherein 1926. Serial No. 112,105.

vfor the purpose of illustration has been disclosed a preferredembodiment of the present invention, the letter A generally indicatesthe present improved oil burner and B the safety moans associatedtherewith for automatically cutting olf the supply of oil thereto.

`rlhe burner A comprises in its construction a suitable base 10 fromwhich rises the supporting standard 11 carrying intermediate its ends, aburner generally indicated by the numeral 12 and which may be of anyconventional or preferred construction. The burner disclosed herein isof the Bunsen type and comprises a circular bottom wall 13 and theannular flared side wall 14. Fitted within the burner 12 and spaced fromthe bottom wall 13 thereof to provide an oil chamber 15 is a block orplate 16 provided with the plurality of burner openings 17. Securedwithin the bottom wall 13 of theburner and communicating with the gaschamber 15 therein is one end of a gas pipe 18, said pipe being providedwith a plurality of alined lighting openings 19 and having its oppositeends communicating with a suitable source of gas supply.

rlhat portion of the standard 11 above the burner 12 is provided with aplurality of vertically disposed flutes 2O which provide flues for thegas emitting from the burner l2. Mounted upon the upper end of thestandard 11 is a hollow frusto-conical gas generator 21 adapted to. beheated by means ofthe burner 12. Leading into one side of the generator21 and communicating therewith is an oil supply pipe 22, the oppositeend thereof communicating with a suitable oil containing tank or thelike 23. Installed within the length of the oil supply pipe 22 is asuitable needle valve 2d, the purpose of which will be setv forth'morefully hereinafter.

rllhe generator 21 is provided at a point diametrically opposite the oilsupply pipe 22 with the substantially vertically disposed gas outletpipe 26 which constitutes al super heater, the upper end of said pipebeing curvedy inwardly and downwardly with the terminal 27 thereofpositioned directly above the flues 2O and carrying the burner nozzle28.'

rlhe burner nozzle 28 is of a novel construction and as disclosed toadvantage in Figure 5, comprises a head 29 having a reduced nipple 30which is threaded within the terminal 27 of the pipe 26. said nippleined l yscale can then be readily removed by simply removing the burnernozzle. Thus, it will be seen that the burner nozzle will be eec-Vtively prevented from clogging and that the terminal lof the gas outletpipe 26 can be quickly and easily cleaned.

In order to operate the present improved oil burner the valve 2l isfirst opened to per- Vmit a small amount of oil to flow into thegenerator 21 after which the gas is turned hito the gas pipe 18 andlighted at the small hole 19. The flame will follow along the series ofopenings lQAuntil it reaches the burner 12 and lights the same. The heatfrom the burner 12 will heat the generator 21 converting the oilcontained therein into a gas, this gas filling up the generator andfinally passing upwardly through the gas outlet pipe 26. Vhen the gaspressure is sulficient to emit at the burner nozzle 18, the flame from`the burner 12 coming up through the flues 2O will ignite the gas comingfrom said burner nozzle and the burner 12 should then be turned off. Theflame from the burner nozzle 2,8 willbe directed against the generator21 which will cause the rapid generation of the gas therein. The flameafter striking the generator 21 is deflected and this heat contactingwith the gas outlet pipe 26 superheats the gas before it leaves theburner nozzle 28 thereby increasing the efficiency of the said burner. Y

lt will of course be understood that alcohol may be used instead of gasfor starting the burner and `Wlien"such alcohol is used, a sufficient-Lamount of it is permitted to flow through the pipe 18 until it reaches apredetermined level in the burner 12. The alcohol is then lighted andthe subsequent operation is the same as has been out-lined above.

The present invention also contemplates the provision of the `novelmeans B for automatically stopping the iiow of oil to the generator 21should the same become flooded due to` the momentary interruption in theroil supply and thegoing out of the burner nozzle. Such means embodies asolenoid 33 mounted upon the oil supply pipe 22 through the medium `of asuitable bracket 34. The solenoid is provided with a slidable plunger'lpivotally connected as at 36 to the needle valve operating arm 37.Leading from the solenoid 33 are the wires 38 and 39, the former beingsuitably secured within the burner plate 16 in the burner 12 while thewire 39 runs to and is connected with a battery 40. Lead- Formedconcentrically goes out due to a momentary interruption in the oilsupply and the oil supply is again resumed, the said oil will lill thegenerator 21 and will pass upwardly through the gas outlet pipe 26 andthrough the burner nozzle 28.

The oil from the burner nozzle will then run through the flues 20filling up the burner 12 and as soon as the level of oil reachestheWires 38 and 41, an electric circuit will be completed through thesolenoid 33 and battery 40. The solenoid will then be energized wherebyto cause the .moving of the plunger and the .closing .of the needlevalve 24.

From the foregoing, it will be appreciated that there has been provideda novel and simplifiedoil burner which will accomplish all of theobjects and perform all ofthe functions enumerated as being desirable inthe statement of the invention set forth hereinabove and it is to befurther understood that. changes in the details ofthe presentinventionmay be resorted to without departing from or sacrificing the Vspiritofthe invention sol long as such changes `fall within the scope oftheappended claims.
